摘　　要：应用地面网与ＧＰＳ网混合平差的方法，将测站归心元素视为地面网的观测值，从而实现了ＧＰＳ测量的归心改正。还给出了一个试验算例，且与无偏心观测的ＧＰＳ网相比较，其结果表明两者精度一致。The method of combined adjustment of GPS net and terrestrial net is applied in this thesis. As elements of centring of a station are regarded as observed value of terrestrial net, an actualization way of correction for centring of GPS net is gotten. An example for off-center observation is given.
